Abstract

PURPOSE:To lock a photosensitive drum securely without special operation by a simple constitution, by locking a photosensitive drum supporting member in a closed block state by utilizing the upper and lower block opening state holding mechanism of a copying machine body. CONSTITUTION:When an upper block 16 is opened, the engagement part 25 of the lever 22 of an opening state holding mechanism extracts the shaft 6 of a photoreceptor 5 for disengaging a handle 26. Then, when a coupling plate 51 is pressed to unlock pawls 52 and 53 and pins 54 and 55 from each other, a drum 5 and a cleaning device 10 rotate clockwise and the projecting parts 43 and 44 of the device are unlocked from the positioning members 49 and 49 of side plates, so that the device 10 and drum 5 can be taken out. Those drum 5 and device 10 are attached by the opposite operation, and thus a photosensitive drum supporting member in a closed block state is locked by the simple constitution without special locking operation by utilizing an upper and lower block opening state holding mechanism, thereby locking the photosensitive drum easily and securely.
